I have recently done quite a bit of researching and I see that some people feel it is more appropriate to spay/neuter dogs around a year and a half to two years of age to insure sexual maturity, and others are more comfortable with 6 months as a minimum age. I have recently spoken to a breeder who is insistent upon neutering at 8 weeks of age. I have never heard of anyone neutering that young? I had asked the breeder the reasoning behind this and told them that I am completely uncomfortable with that. Anyone have info about this?
